There is often the challenge of simply spending too little to get effective feedback, but at $10k that's often a number I've seen that starts to make a difference. Are you spending this all on Google Adwords?

The first number to consider is 0. No sales on $10k is highly indicative. But even a couple sales (let's say you had a $50 product) is also pretty bad from a ratio standpoint. Can you share how much revenue you've generated from $10k in spend?
